JOEL S. WHITEHURST, OF SAN JOSE, CALIFORNIA.

SASH-FASTENER.

Application filed April 14, 1913.

To all whom it may concern:

Be it known that I, J OEL S. VVHITEHURsT, a citizen of the UnitedStates, residing at 303 Minnesota avenue, San Jose, in the county ofSanta Clara and State of California, have invented a new and usefulImprovement in Sash-Fasteners, of which the following is aspecification.

My invention relates to improvements in sash fasteners, and the objectsof my invention are to construct a more economical sash fastener, and toconstruct a sash fastener by which the window may be more securelylocked than is now the case with most of the fasteners now on themarket.

I obtain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a front elevation of a window frame andsashes with my device in position, parts being broken away. Fig. 2 is aside elevation of a window frame with my device in position, parts beingbroken away. Fig. 3 is a sectional view on line A-A, Fig. 2.

The upper sash is marked 1, the lower sash 2 and the casing 3. My sashfastener is operated at the point of meeting of the two sashes, at oneside of the casing, by turning key 4. This key passes into casing 3 andhas a bearing 5 in the rear of said casing. Key 4 passes throughescutcheon 6, countersunk in the face of easing 3. The end of key 4,next to bearing 5, is square, and passes through a square hole intumbler 7. The rounded part of tumbler 7 is shown facing sashes 1 and 2at their point of meeting. This tumbler turns in channel 7 cut in casing3. The ends of the bolt levers, 8 and 8 rest on and bear against theopposite or flat side of tumbler 7. Bolt lever 8, with its lower endresting on, and bearing against, the uper portion of said fiat side,passes upward therefrom, as shown at Fig. 3. At the lower end of lever8, passing through an oblong slot 9, Fig. 2, is a bolt 10. This bolt isflattened at this end to give it suflicient play in slot 9, withshoulders bearing against the inner side of lever 8, and a pin passingthrough its end on the outer side of said lever to hold it in place inslot 9. This pin is marked 11 in Fig. 2. Lever 8 has bearings 12 at itsupper end secured in casing 3. The looped end of spring 13 bears againstthe outer face of lever 8 a distance from the upper end thereof. Theends of spring 13 are coiled around the bearing pin Specification ofLetters Patent.

14, and bear against the side of casing 3, as shown at Fig. 2. I place aperforated strip of metal 15 on the edge of the window sashes, withholes therein at predetermined distances from each other, and bolt 10passes in and out of these holes as the sash is locked or unlocked. Thelower sash and sash lock are provided with like parts, and bear the samenumerals, except that the letter a is applied thereto in addition tosaid numerals. Bolt lever 8 extends downward from tumbler 7, and thespring 13 is located at the lower end thereof, and the bolt 10 at theupper end. The sashes fit sufficiently snug in the casing to prevent thesash from lowering of its own weight when the bolts are removed. Thesashes are raised and lowered by hand. My sash fastener is operated byturning the button 16 on key 4. When both of the bolts are entered inthe holes of the metallic strips in the upper and lower sashes thetumbler 7 stands perpendicular in position, and by turning button 16 tothe right the tumbler 7 pushes the lower end of lever 8 outward and bolt10 is removed from a hole in strip 15. The upper sash is then lowered tothe desired point and the button 16 is turned to its proper position,thus fastening the upper sash at the desired point. The lower sash israised by turning button 16 to the left.

Having thus described my invention, what I claim is 1. In a sashfastener, the combination of a casing, a sash, a perforated stripsecured in the edge of said sash, a semi-circular tumbler located in achannel in said casing, a bolt lever, equal in length, parallel withsaid sash, one end thereof bearing against the flat side of said tumblerand having bearings at its opposite end, a spring looped over andbearing against said lever at the bearing end thereof, a bolt looselysecured in a slot in said lever adjacent to said tumbler, passinginwardly and adapted to engage the perforations in said strip, and a keyfor turning said tumbler.

2. In a sash fastener, the combination of a casing, an upper and a lowersash, a perforated strip secured in the edge of each sash, asemi-circular tumbler, located in a channel in said casing at the pointof meeting of said sashes, extending in part upward and downward fromsaid point of meeting, bolt levers, parallel with said sashes, extendingin opposite direction the full length cent to said tumbler, and a keypassing of said sashes, one end of each lever extendthrough saidtumbler. for operating the ing over and bearing against the flat side ofsaid tumbler a distance, hearings in the same.

opposite end of each lever, a spring looped JOEL S. WHITEHURST. over andbearing against the outer side of Witnesses:

each lever at the bearing end thereof, a bolt JOHN A. NAISMITH,

loosely secured in a slot in each lever adja- F. C. BATES.
